I'm a complete newbie to Ubuntu, but so far, I've had no luck installing a software RAID5 with Ubuntu. I've already installed Ubuntu Server 11.04 about 3 times. I followed the software raid instructions here to the best of my abilities, even though the screens are different. I did not use a RAID 1 for my boot partition on each drive...is that a must?
Anyway, I've had errors in past installations, but I was able to get through the entire install with 3 drives, a small bootable partition on each (sda/b/c1?), a swap partition on each (sda/b/c3), and then a large partition mounted to / for my RAID 5 (sda/b/c2). The final install step looks like everything works correctly because Ubuntu says it is installing GRUB to /dev/sda1 through /dev/sdc1, but then when I try to boot for the first time, it immediately says "error: no such disk GRUB recovery>".
I was able to login using LiveCD and try to get Grub loaded, but I haven't had any luck there as well. If I apt-get grub and run it and issue find /boot/grub/stage1
, it says nothing is found. What am I doing wrong, how do I get to a working Raid5?
